Patchcord Extralink SC/APC to LC/UPC, Singlemode Duplex G.652D, 3 mm, 0.5 m

Patchcord Extralink SC/APC to LC/UPC, Singlemode Duplex G.652D, 3 mm, 0.5 m is a singlemode duplex fiber patch cable designed for short interconnections in telecom, data center and FTTH environments. The cable uses ITU-T G.652D singlemode optical fibre in a 3 mm outdoor/indoor-rated construction and is terminated with an SC/APC connector on one end and an LC/UPC connector on the other. The 0.5 m total length provides a compact duplex link suitable for patch panels, optical distribution frames (ODFs) and direct equipment connections where APC-to-UPC terminations are required.

Advantages

This patchcord provides low-loss, polarization-stable singlemode connectivity with APC-to-UPC mating that helps reduce return loss at the SC/APC interface while maintaining reliable LC/UPC performance. The duplex configuration supports bidirectional fiber pairs in a single cable jacket for tidy cable management. Its 3 mm cable diameter balances mechanical robustness and flexibility for routing inside cabinets and enclosures, and the precision-terminated connectors ensure repeatable optical performance and easy installation.

Suitable for

• Interconnecting optical equipment such as OLT, ONU/ONT, switches and media converters
• Patch panels and optical distribution frames (ODF)
• FTTH drop and indoor cabling requiring APC-to-UPC terminations
• Short-distance duplex links in telecom rooms and data centers

Key specifications

• Fiber type: singlemode, G.652D (ITU-T)
• Configuration: duplex (two fibers in one jacket)
• Cable diameter: 3.0 mm
• Connectors: SC/APC on one end, LC/UPC on the other
• Polishing: APC on SC (angled), UPC on LC (ultra-polished)
• Length: 0.5 m total
• Typical application: indoor/FTTH and data center patching

How to use

Route the patchcord along cable management paths to avoid sharp bends and excessive tensile stress. Align and insert the SC/APC connector into the corresponding APC adapter or port, ensuring the keyed orientation engages correctly; then connect the LC/UPC connector into the matching UPC adapter or port. Verify the duplex polarity and correct fiber pairing before powering optical equipment. For best performance, keep connector endfaces clean and inspect or clean with appropriate fiber-optic cleaning tools prior to connection.

Recommendations

Store the patchcord coiled loosely and avoid bending below the specified minimum bend radius. Use dust caps when connectors are not in use and perform endface cleaning with lint-free wipes and approved solvents to maintain low insertion loss and high return loss performance for SC/APC and LC/UPC interfaces.
